What are aerosols?

Aerosols are defined as very fine solid or liquid particulates that are suspended in the atmosphere. These tiny particles can originate from various sources, including natural ones like volcanic eruptions and man-made sources such as combustion processes and industrial activities. The size of aerosols influences their behavior in the atmosphere and their effects on air quality and climate. For instance, they can scatter and absorb sunlight, impact cloud formation, and affect human health when inhaled. Understanding aerosols is crucial for studying air pollution and its implications on both ecological and human health, as they can carry various pollutants and contribute to respiratory issues.
